Ruhsuz beden nasil ölüyse, eylemsiz iman da ölüdür.Ruh is, I believe, a cognate with the Hebrew word for spirit. That's what it means, anyhow. As a body (beden) sans spirit is dead, even so faith sans works is dead.
Which means -- for those of us who live in terms of our faith, it is way too easy to slip into a fantasy world. If we are not acting on what we believe, we are amusing ourselves within the playgrounds of our imaginations. You may have seen the movie A Beautiful Mind. The protagonist took vacations into a parallel universe, wherein he was at the center of a global conspiracy, and the world depended on what he did next. He was also schizophrenic.
May God have mercy upon us.
